⚠️ Safety Warnings
Important safety information - read before proceeding
- •Always work on a flat surface and engage the parking brake.
- •Wear safety goggles and gloves.
- •Use the jack to lift the vehicle and support it securely with jack stands.
- •Remove the wheel using the lug wrench.
- •Locate the caliper mounting bolts and remove them using a socket.
- •Carefully slide the caliper off the brake rotor. Do not disconnect the brake line; instead, support the caliper with a bungee cord or hang it to avoid straining the brake line.
- •Remove the old brake pads from the caliper bracket.
- •Use the C-clamp or brake caliper tool to compress the caliper piston back into the caliper housing. This step is necessary to accommodate the new, thicker pads.
- •Install the new brake pads in the caliper bracket, ensuring they are positioned correctly.
- •Slide the caliper back over the new brake pads and rotor.
- •Reinstall the caliper mounting bolts and tighten them to the manufacturer's specifications (typically around 25-35 Nm, but verify in the service manual).
- •Place the wheel back onto the hub and hand-tighten the lug nuts.
- •Lower the vehicle from the jack stands using the jack.
- •Once the vehicle is on the ground, use the torque wrench to tighten the lug nuts to the manufacturer's specifications (typically around 120 Nm).
- •Pump the brake pedal several times to seat the new pads against the rotors.
- •Test drive the vehicle at low speed to ensure proper brake function and listen for any abnormal noises.
- •Check for any brake fluid leaks around the caliper.
- •Regularly inspect brake pads and rotors during maintenance.
- •Use high-quality brake pads and components to extend lifespan.
- •Follow the manufacturer's recommended maintenance schedule for brake system checks.
